Up for sale is my mint AR preamp which I purchased from an authorized dealer approx 2 years ago. The preamp is in mint condition with about 3300 hours on tubes. Also included are brand new tubes. All original packaging, manual, remote, and cord included. As common with these, the remote battery door has weak latching. Check my feedback and buy with confidence. Pay pal add 3%.
